Rotational Spectroscopy, Tentative Interstellar Detection, and Chemical Modelling of N-methylformamide
N-methylformamide, CH3NHCHO, may be an important molecule for interstellar pre-biotic chemistry because it contains a peptide bond. The rotational spectrum of the most stable trans conformer of CH3NHCHO is complicated […]

First Detection of Methyl Isocyanate (CH3NCO) in a Solar-type Protostar
We report the first detection of the prebiotic complex organic molecule CH3NCO in a solar-type protostar, IRAS16293-2422 B. This species is one of the most abundant complex organic molecule detected […]

Meteorites and the RNA World: A Thermodynamic Model of Nucleobase Synthesis within Planetesimals
The possible meteorite parent body origin of Earth’s pregenetic nucleobases is substantiated by the guanine (G), adenine (A) and uracil (U) measured in various meteorites. Cytosine (C) and thymine (T) […]
